Maxibright Daylight 660W PRO LED is a flagship 660W bar LED grow light built for growers who want serious output, uniform canopy coverage and proper value for money. Designed for 1.5m x 1.5m grow tents and rooms, it combines a high-output 6-bar layout with full spectrum performance, passive cooling and controller compatibility in one streamlined fixture.
With a PPF of 1782 µmol/s and 2.7 µmol/J fixture efficiency, the Daylight 660W PRO gives you the intensity needed for aggressive growth and heavy flowering, while staying cooler and more efficient than traditional HID lighting.
Please note: This item is purchased to order, so delivery or local collection may take slightly longer than usual.
If you are lighting a 1.5m x 1.5m space properly, coverage matters just as much as raw power. Compact fixtures and lens-led designs can leave you with hotspots directly under the light and weaker intensity around the edges.
The Daylight 660W PRO solves that with a wide 6-bar layout that physically spreads the diodes across the canopy. That gives you more even PPFD, better plant-to-plant consistency and improved use of your full grow area.
It is also a smart upgrade path from a 600W HPS. You get more usable light, lower excess heat and quieter operation, without stepping into the price bracket of some premium commercial fixtures.
Instead of concentrating all the light into one tight central point, the Daylight 660W PRO uses 6 LED bars to spread output across the entire footprint. That means more of your plants sit directly under a light source, helping reduce hotspots, improve edge performance and create a more uniform canopy.
Because the light is distributed across the fixture rather than pushed outward from a small centre, you also lose less usable light to walls and tent sides.
This fixture uses a full spectrum white light with added red, giving you a balanced output for propagation, veg and flowering. The added red helps drive stronger bloom performance, while the broad white spectrum supports healthy full-cycle growth.
Built with LUMLED white diodes and Osram red diodes, it is designed to deliver both intensity and spectral quality without overcomplicating the setup.
The Daylight 660W PRO uses passive heatsink cooling, so there are no internal fans, no added noise and fewer moving parts to fail. That keeps the fixture silent, lowers maintenance and improves long-term reliability.
If you are moving from HPS to a high-output bar LED, start slightly higher above the canopy or on a lower dimmer setting, then increase intensity as plants adapt. You will usually get better results from easing plants into the extra usable light rather than hitting them with full power straight away.
Would this be ok in a 1.2x1.2x2.2 tent? Or would it be too much?
This light would be perfect in that tent. The footprint is exactly right for the ground space and the extra height you have in a high ceiling tent make it ideal.
